CROSS-REFERENCE TO RELATED PATENT APPLICATIONS

This application claims priority from Provisional U.S. Patent Application 61/759,641, filed Feb. 1, 2013, titled Systems and Methods for Display of Supplemental Content Responsive To Micro-Location, and U.S. Patent Application 61/822,568, filed May 13, 2013, titled Systems and Methods for Display of Supplemental Content Responsive To Micro-Location, each of which are incorporated herein by reference in their entirety.

BACKGROUND OF THE DISCLOSURE

The merchandise offered by local and national suppliers is always changing. Customers often spend numerous hours browsing websites, magazines, and other media outlets before purchasing merchandise, but unfortunately, many customers still cannot stay abreast of the latest trends and newest products. Additionally, local and national suppliers often fail to deliver a personalized shopping experience to consumers.

BRIEF SUMMARY OF THE DISCLOSURE

The present disclosure provides a system and method for providing a user with supplemental content based on the user's preferences and location. Furthermore, the disclosure provides a computer program that allows users to discover the latest trends, discover new stores, and organize their discoveries from a platform that is accessible from a mobile device or computer.

The system provides the user with a platform to store, organize, and retrieve preferences. The preferences may include preferred styles, looks, and retailers. Saving the preferences allows the user to create a customized catalog of styles, offers, and content.

Additionally, the system includes one or more beacons that enables the detection of a device's location. Based on the location, the system may use the user's stored preferences to provide the user with supplemental content. Because the system can determine the user's location, the system can determine what merchandise the user is most likely viewing. Accordingly, the system can provide the customer with such supplemental content as matching accessories, time sensitive discounts on the item, or additional information about the item.

According to one aspect of the disclosure, a system for determining a micro-location includes a server. The server is configured to receive data. The data includes an encrypted data packet, a key hint, and an indication of a client position. The server is also configured to select a key to decrypt the encrypted data packet responsive to the key hint and the indication of the client position, and decrypt the encrypted data packet. The server is further configured to retrieve a beacon identification from the decrypted data packet, and determine a micro-location of the client responsive to the beacon identification. The server is also configured to transmit the determined micro-location to the client.

In some implementations, the key hint is non-unique. The indication of the client position can be one of a geo-hash of a global positioning coordinate, a global positioning coordinate, or a network service set identifier (SSID).

In some implementations, the encrypted data packet is encrypted with a 16-bit AES key and the encrypted data packed is only one block of AES data long. The key hint can be a truncated copy of the key to decrypt the encrypted data packet. In some implementations, the server updated the key at predetermined intervals.

In some implementations, the server is configured to determine the micro-location of the client by generating a hash with the beacon identification and use the hash to retrieve the micro-location from a hash table.

According to another aspect of the disclosure, a method for determining a micro-location includes receiving, by a server, data. The data can include an encrypted data packet, a key hint, and an indication of a client position. The method also includes selecting, by the server, a key to decrypt the encrypted data packet responsive to the key hint and the indication of the client position, and decrypting the encrypted data packet. The method also includes retrieving a beacon identification from the decrypted data packet, and determining a micro-location of the client responsive to the beacon identification. Once the micro-location is determined, supplemental content is transmitted to the client responsive to the determined micro-location.

In some implementations, the key hint is non-unique. The indication of the client position can be one of a geo-hash of a global positioning coordinates, a global positioning coordinate, or a network service set identifier (SSID).

In some implementations, the encrypted data packet is encrypted with a 16-bit AES key and the encrypted data packed is only one block of AES data long. The key hint can be a truncated copy of the key to decrypt the encrypted data packet. In some implementations, the server updated the key at predetermined intervals.

In some implementations, the method also includes determining the micro-location of the client by generating a hash with the beacon identification and use the hash to retrieve the micro-location from a hash table.

One aspect of the disclosure relates to a computer readable medium storing processor executable instructions. When the instructions are executed by a processor, the instructions cause the processor to receive data. The data includes an encrypted data packet, a key hint, and an indication of a client position. The server is also configured to select a key to decrypt the encrypted data packet responsive to the key hint and the indication of the client position, and decrypt the encrypted data packet. The server is further configured to retrieve a beacon identification from the decrypted data packet, and determine a micro-location of the client responsive to the beacon identification. The server is also configured to transmit the determined micro-location to the client.

A. Computing and Network Environment

Prior to discussing specific embodiments of the present solution, it may be helpful to describe aspects of the operating environment as well as associated system components (e.g., hardware elements) in connection with the methods and systems described herein. Referring to FIG. 1A, an embodiment of a network environment is depicted. In brief overview, the network environment includes one or more client devices 102 a-102 n (also generally referred to as local machine(s) 102, client(s) 102, client node(s) 102, client machine(s) 102, client computer(s) 102, client device(s) 102, endpoint(s) 102, or endpoint node(s) 102) in communication with one or more servers 106 a-106 n (also generally referred to as server(s) 106, node 106, or remote machine(s) 106) via one or more networks 104. In some embodiments, a client device 102 has the capacity to function as both a client node seeking access to resources provided by a server and as a server providing access to hosted resources for other client devices 102 a-102 n.

Although FIG. 1A shows a network 104 between the client devices 102 and the servers 106, the client devices 102 and the servers 106 may be on the same network 104. In some embodiments, there are multiple networks 104 between the client devices 102 and the servers 106. In one of these embodiments, a network 104′ (not shown) may be a private network and a network 104 may be a public network. In another of these embodiments, a network 104 may be a private network and a network 104′ a public network. In still another of these embodiments, networks 104 and 104′ may both be private networks.

The network 104 may be connected via wired or wireless links. Wired links may include Digital Subscriber Line (DSL), coaxial cable lines, or optical fiber lines. The wireless links may include BLUETOOTH, Wi-Fi, Worldwide Interoperability for Microwave Access (WiMAX), an infrared channel or satellite band. The wireless links may also include any cellular network standards used to communicate among mobile devices, including standards that qualify as 1G, 2G, 3G, or 4G. The network standards may qualify as one or more generation of mobile telecommunication standards by fulfilling a specification or standards such as the specifications maintained by International Telecommunication Union. The 3G standards, for example, may correspond to the International Mobile Telecommunications-2000 (IMT-2000) specification, and the 4G standards may correspond to the International Mobile Telecommunications Advanced (IMT-Advanced) specification. Examples of cellular network standards include AMPS, GSM, GPRS, UMTS, LTE, LTE Advanced, Mobile WiMAX, and WiMAX-Advanced. Cellular network standards may use various channel access methods e.g. FDMA, TDMA, CDMA, or SDMA. In some embodiments, different types of data may be transmitted via different links and standards. In other embodiments, the same types of data may be transmitted via different links and standards.

The network 104 may be any type and/or form of network. The geographical scope of the network 104 may vary widely and the network 104 can be a body area network (BAN), a personal area network (PAN), a local-area network (LAN), e.g. Intranet, a metropolitan area network (MAN), a wide area network (WAN), or the Internet. The topology of the network 104 may be of any form and may include, e.g., any of the following: point-to-point, bus, star, ring, mesh, or tree. The network 104 may be an overlay network which is virtual and sits on top of one or more layers of other networks 104′. The network 104 may be of any such network topology as known to those ordinarily skilled in the art capable of supporting the operations described herein. The network 104 may utilize different techniques and layers or stacks of protocols, including, e.g., the Ethernet protocol, the internet protocol suite (TCP/IP), the ATM (Asynchronous Transfer Mode) technique, the SONET (Synchronous Optical Networking) protocol, or the SDH (Synchronous Digital Hierarchy) protocol. The TCP/IP internet protocol suite may include application layer, transport layer, internet layer (including, e.g., IPv6), or the link layer. The network 104 may be a type of a broadcast network, a telecommunications network, a data communication network, or a computer network.

In some embodiments, the system may include multiple, logically-grouped servers 106. In one of these embodiments, the logical group of servers may be referred to as a server farm 38 or a machine farm 38. In another of these embodiments, the servers 106 may be geographically dispersed. In other embodiments, a machine farm 38 may be administered as a single entity. In still other embodiments, the machine farm 38 includes a plurality of machine farms 38. The servers 106 within each machine farm 38 can be heterogeneous—one or more of the servers 106 or machines 106 can operate according to one type of operating system platform (e.g., WINDOWS NT, manufactured by Microsoft Corp. of Redmond, Wash.), while one or more of the other servers 106 can operate on according to another type of operating system platform (e.g., Unix, Linux, or Mac OS X).

In one embodiment, servers 106 in the machine farm 38 may be stored in high-density rack systems, along with associated storage systems, and located in an enterprise data center. In this embodiment, consolidating the servers 106 in this way may improve system manageability, data security, the physical security of the system, and system performance by locating servers 106 and high performance storage systems on localized high performance networks. Centralizing the servers 106 and storage systems and coupling them with advanced system management tools allows more efficient use of server resources.

The servers 106 of each machine farm 38 do not need to be physically proximate to another server 106 in the same machine farm 38. Thus, the group of servers 106 logically grouped as a machine farm 38 may be interconnected using a wide-area network (WAN) connection or a metropolitan-area network (MAN) connection. For example, a machine farm 38 may include servers 106 physically located in different continents or different regions of a continent, country, state, city, campus, or room. Data transmission speeds between servers 106 in the machine farm 38 can be increased if the servers 106 are connected using a local-area network (LAN) connection or some form of direct connection. Additionally, a heterogeneous machine farm 38 may include one or more servers 106 operating according to a type of operating system, while one or more other servers 106 execute one or more types of hypervisors rather than operating systems. In these embodiments, hypervisors may be used to emulate virtual hardware, partition physical hardware, virtualize physical hardware, and execute virtual machines that provide access to computing environments, allowing multiple operating systems to run concurrently on a host computer. Native hypervisors may run directly on the host computer. Hypervisors may include VMware ESX/ESXi, manufactured by VMWare, Inc., of Palo Alto, Calif.; the Xen hypervisor, an open source product whose development is overseen by Citrix Systems, Inc.; the HYPER-V hypervisors provided by Microsoft or others. Hosted hypervisors may run within an operating system on a second software level. Examples of hosted hypervisors may include VMware Workstation and VIRTUALBOX.

Management of the machine farm 38 may be de-centralized. For example, one or more servers 106 may comprise components, subsystems and modules to support one or more management services for the machine farm 38. In one of these embodiments, one or more servers 106 provide functionality for management of dynamic data, including techniques for handling failover, data replication, and increasing the robustness of the machine farm 38. Each server 106 may communicate with a persistent store and, in some embodiments, with a dynamic store.

Server 106 may be a file server, application server, web server, proxy server, appliance, network appliance, gateway, gateway server, virtualization server, deployment server, SSL VPN server, or firewall. In one embodiment, the server 106 may be referred to as a remote machine or a node. In another embodiment, a plurality of nodes 290 may be in the path between any two communicating servers.

Referring to FIG. 1B, a cloud computing environment is depicted. A cloud computing environment may provide client device 102 with one or more resources provided by a network environment. The cloud computing environment may include one or more client devices 102 a-102 n, in communication with the cloud 108 over one or more networks 104. Client devices 102 may include, e.g., thick clients, thin clients, and zero clients. A thick client may provide at least some functionality even when disconnected from the cloud 108 or servers 106. A thin client or a zero client may depend on the connection to the cloud 108 or server 106 to provide functionality. A zero client may depend on the cloud 108 or other networks 104 or servers 106 to retrieve operating system data for the client device. The cloud 108 may include back end platforms, e.g., servers 106, storage, server farms or data centers.

The cloud 108 may be public, private, or hybrid. Public clouds may include public servers 106 that are maintained by third parties to the client devices 102 or the owners of the clients. The servers 106 may be located off-site in remote geographical locations as disclosed above or otherwise. Public clouds may be connected to the servers 106 over a public network. Private clouds may include private servers 106 that are physically maintained by client devices 102 or owners of clients. Private clouds may be connected to the servers 106 over a private network 104. Hybrid clouds 108 may include both the private and public networks 104 and servers 106.

The cloud 108 may also include a cloud based delivery, e.g. Software as a Service (SaaS) 110, Platform as a Service (PaaS) 112, and Infrastructure as a Service (IaaS) 114. IaaS may refer to a user renting the use of infrastructure resources that are needed during a specified time period. IaaS providers may offer storage, networking, servers or virtualization resources from large pools, allowing the users to quickly scale up by accessing more resources as needed. Examples of IaaS include AMAZON WEB SERVICES provided by Amazon.com, Inc., of Seattle, Wash., RACKSPACE CLOUD provided by Rackspace US, Inc., of San Antonio, Tex., Google Compute Engine provided by Google Inc. of Mountain View, Calif., or RIGHTSCALE provided by RightScale, Inc., of Santa Barbara, Calif. PaaS providers may offer functionality provided by IaaS, including, e.g., storage, networking, servers or virtualization, as well as additional resources such as, e.g., the operating system, middleware, or runtime resources. Examples of PaaS include WINDOWS AZURE provided by Microsoft Corporation of Redmond, Wash., Google App Engine provided by Google Inc., and HEROKU provided by Heroku, Inc. of San Francisco, Calif. SaaS providers may offer the resources that PaaS provides, including storage, networking, servers, virtualization, operating system, middleware, or runtime resources. In some embodiments, SaaS providers may offer additional resources including, e.g., data and application resources. Examples of SaaS include GOOGLE APPS provided by Google Inc., SALESFORCE provided by Salesforce.com Inc. of San Francisco, Calif., or OFFICE 365 provided by Microsoft Corporation. Examples of SaaS may also include data storage providers, e.g. DROPBOX provided by Dropbox, Inc. of San Francisco, Calif., Microsoft SKYDRIVE provided by Microsoft Corporation, Google Drive provided by Google Inc., or Apple ICLOUD provided by Apple Inc. of Cupertino, Calif.

Client devices 102 may access IaaS resources with one or more IaaS standards, including, e.g., Amazon Elastic Compute Cloud (EC2), Open Cloud Computing Interface (OCCI), Cloud Infrastructure Management Interface (CIMI), or OpenStack standards. Some IaaS standards may allow clients access to resources over HTTP, and may use Representational State Transfer (REST) protocol or Simple Object Access Protocol (SOAP). Client devices 102 may access PaaS resources with different PaaS interfaces. Some PaaS interfaces use HTTP packages, standard Java APIs, JavaMail API, Java Data Objects (JDO), Java Persistence API (JPA), Python APIs, web integration APIs for different programming languages including, e.g., Rack for Ruby, WSGI for Python, or PSGI for Perl, or other APIs that may be built on REST, HTTP, XML, or other protocols. Client devices 102 may access SaaS resources through the use of web-based user interfaces, provided by a web browser (e.g. GOOGLE CHROME, Microsoft INTERNET EXPLORER, or Mozilla Firefox provided by Mozilla Foundation of Mountain View, Calif.). Client devices 102 may also access SaaS resources through smartphone or tablet applications, including, e.g., Salesforce Sales Cloud, or Google Drive app. Client devices 102 may also access SaaS resources through the client operating system, including, e.g., Windows file system for DROPBOX.

In some embodiments, access to IaaS, PaaS, or SaaS resources may be authenticated. For example, a server or authentication server may authenticate a user via security certificates, HTTPS, or API keys. API keys may include various encryption standards such as, e.g., Advanced Encryption Standard (AES). Data resources may be sent over Transport Layer Security (TLS) or Secure Sockets Layer (SSL).

The client device 102 and server 106 may be deployed as and/or executed on any type and form of computing device, e.g. a computer, network device or appliance capable of communicating on any type and form of network and performing the operations described herein. FIGS. 1C and 1D depict block diagrams of a computing device 100 useful for practicing an embodiment of the client device 102 or a server 106. As shown in FIGS. 1C and 1D, each computing device 100 includes a central processing unit 121, and a main memory unit 122.

The storage device 128 may include, without limitation, an operating system, software, and a software of a Pinpoint System Server 120. As shown in FIG. 1D, each computing device 100 may also include additional optional elements, e.g. a memory port 103, a bridge 170, one or more input/output devices 130 a-130 n (generally referred to using reference numeral 130), and a cache memory 140 in communication with the central processing unit 121.

The central processing unit 121 is any logic circuitry that responds to and processes instructions fetched from the main memory unit 122. In many embodiments, the central processing unit 121 is provided by a microprocessor unit, e.g.: those manufactured by Intel Corporation of Mountain View, Calif.; those manufactured by Motorola Corporation of Schaumburg, Ill.; the ARM processor and TEGRA system on a chip (SoC) manufactured by Nvidia of Santa Clara, Calif.; the POWER7 processor, those manufactured by International Business Machines of White Plains, N.Y.; or those manufactured by Advanced Micro Devices of Sunnyvale, Calif. The computing device 100 may be based on any of these processors, or any other processor capable of operating as described herein. The central processing unit 121 may utilize instruction level parallelism, thread level parallelism, different levels of cache, and multi-core processors. A multi-core processor may include two or more processing units on a single computing component. Examples of a multi-core processors include the AMD PHENOM IIX2, INTEL CORE i5 and INTEL CORE i7.

In some embodiments, the main memory 122 or the storage 128 may be non-volatile; e.g., non-volatile read access memory (NVRAM), flash memory non-volatile static RAM (nvSRAM), Ferroelectric RAM (FeRAM), Magnetoresistive RAM (MRAM), Phase-change memory (PRAM), conductive-bridging RAM (CBRAM), Silicon-Oxide-Nitride-Oxide-Silicon (SONOS), Resistive RAM (RRAM), Racetrack, Nano-RAM (NRAM), or Millipede memory. The main memory 122 may be based on any of the above described memory chips, or any other available memory chips capable of operating as described herein. In the embodiment shown in FIG. 1C, the processor 121 communicates with main memory 122 via a system bus 150 (described in more detail below). FIG. 1D depicts an embodiment of a computing device 100 in which the processor communicates directly with main memory 122 via a memory port 103. For example, in FIG. 1D the main memory 122 may be DRDRAM.

FIG. 1D depicts an embodiment in which the main processor 121 communicates directly with cache memory 140 via a secondary bus, sometimes referred to as a backside bus. In other embodiments, the main processor 121 communicates with cache memory 140 using the system bus 150. Cache memory 140 typically has a faster response time than main memory 122 and is typically provided by SRAM, BSRAM, or EDRAM. In the embodiment shown in FIG. 1D, the processor 121 communicates with various I/O devices 130 via a local system bus 150. Various buses may be used to connect the central processing unit 121 to any of the I/O devices 130, including a PCI bus, a PCI-X bus, or a PCI-Express bus, or a NuBus. For embodiments in which the I/O device is a video display 124, the processor 121 may use an Advanced Graphics Port (AGP) to communicate with the display 124 or the I/O controller 123 for the display 124. FIG. 1D depicts an embodiment of a computer 100 in which the main processor 121 communicates directly with I/O device 130 b or other processors 121′ via HYPERTRANSPORT, RAPIDIO, or INFINIBAND communications technology. FIG. 1D also depicts an embodiment in which local busses and direct communication are mixed: the processor 121 communicates with I/O device 130 a using a local interconnect bus while communicating with I/O device 130 b directly.

B. System for Determining Location and Delivering Content

The present disclosure is directed towards systems and methods for providing supplemental content to a user based on the user's location and preferences. In some implementations, the system and methods described herein are implemented with the computer and network environment of FIGS. 1A-1D. As described herein, a user's location can include the user's micro-location within the premises of a store, building, or outdoor location. For example, the system may narrow the location of a client device to a specific section within a store.

While the system and methods have been particularly shown and described with reference to specific implementations, it should be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the system and methods described in this disclosure.

FIG. 2A is a schematic representation of a Pinpoint Network (PN) 200 for delivering content responsive to a client's location. As a brief overview, the PN 200 includes a Pinpoint System Server (PSS) 120. The PSS 120 may include a plurality of components and modules. These modules may include an anti-spoofing module 261, a logistics module 262, user interface module 263, and an analysis module 264. Additionally, the PSS 120 includes at least one database. The databases may include a beacon location database 265, a content database 266, a user preference database 267, and a content provider database 268.

The PN 200 can also include a plurality of client devices 102 each in use by a user 230. The client devices 102 may include a camera 221, a GPS module 222, and a wireless module 223. The PN 200 also includes at least one beacon 240. The beacon 240 includes a wireless module 241 for communicating with the client device 102 (or PSS 120), an anti-spoofing module 242, and a battery 243. Additionally, the PN 200 includes at least one content provider 250 that provides supplemental content 251 to the PSS 120. The PSS 120 delivers supplemental content 251 to the plurality of client devices 102. The above described components of the PN 200 are connected by a network 104.

In some implementations, the content provider 250 a merchant that sells merchandise (or more generically referred to as content) to customers or users. In some implementations, the supplemental content 251 is associated with the content for sell by the content provider 250. For example, the content provider 250 may be a clothing store selling content such as women's and men's fashions. In this example, the supplemental content 251 may include information or other digital content related to the fashions for sell by the clothing store. The content provider 250 may place a beacon 240 near specific content in the content provider's store. For example, the content provider 250 may place a first beacon 240 near a display of sweaters and a second beacon 240 near a rack of women's jeans. In other implementations, the beacon 240 may be also placed near a non-content item, such as a door, cash register, or be positioned such that the beacon 240 is near a plurality of content items. The PSS 120 may deliver supplemental content 251 to a client device 102 when the PSS 120 determines the client device 102 is within a predetermined proximity of a beacon 240.

The beacon 240 includes a wireless module 241, an anti-spoofing module 242, and a battery 243. The wireless module 241 may be a WIFI radio, a Bluetooth radio, RFID tag and/or similar wireless transmitter or receiver. In some implementations, the wireless module 241 is only a wireless transmitter. For example, the beacon 240 may broadcast a signal that is detected by the client device 102, but may not receive a signal from the client device 102. The wireless module 241 may be a low power wireless module such as a Bluetooth 4.0 (i.e., low energy) radio. Additionally or alternatively, the wireless module 241 may cycle on and off to conserve energy. In some implementations, the cycling may occur based on time of day or the detection of a nearby user. The beacon 240 may be configured to only broadcast a wireless signal during business hours. In some implementations, the wireless module 241 emits a wireless signal that covers a predetermined proximity zone. As described in greater detail below, the beacon 240 may broadcast a unique beacon identification number over the wireless signal, which is detected by the client device 102. In some implementations, the size and shape of the proximity zone may be adjusted. For example the size of the proximity zone may be adjusted by altering the power level of the wireless signal. For example, the power level of the wireless signal may be set to one of 4 dB, 0 dB, −6 dB, or −23 dB.

In some implementations, the beacon identification number is a unique identifier number that may not be detected if one is outside the defined proximity zone. In some implementations, a plurality of beacons 240 may be daisy chained together such that they create a unified proximity zone. For example, a content provider 250 may wish to have a single proximity zone cover an entire store rather than having micro proximity zones distributed throughout the store. In this example, each of the daisy changed Beacons 240 broadcast the same Beacon identification number.

Only able to detect the beacon identification number within the proximity zone allows the PSS 120 to determine a location of the client device 102. For example, and as described in greater detail below, if the client is detecting the beacon identification number 39475423, then the client must be within the proximity zone of the beacon 240 having the identification number of 39475423. Accordingly, the PSS 120 may associate the location of the beacon 240 with the client device 102.

In some implementations, the wireless module 241 allows the beacon 240 to communicate directly with the PSS 120 via the network 104. In other implementations, as in the implementation of FIG. 2A, the beacon 240 does not communicate directly with the PSS 120, but rather passes data to the client device 102, which then forwards the data to the PSS 120. The method of forwarding data from the Beacon 240 to the PSS 120, via a client device 102, is discussed in greater detail in relation to FIGS. 2B-3B.

In some implementations, the data transmitted from a beacon 240 to the client device 102 or PSS 120 is encrypted, for example, with 16 byte AES encryption. The data may include an AES key identifier, a beacon ID, a MAC address, the current battery level, beacon uptime, data, random data, or any combination thereof. The beacon ID may be randomly generated, and in some implementations, updated at specific intervals. For example, the beacon ID may be generated using a function (e.g., a hash function), which generates a new beacon ID at periodic intervals. The PSS 120 may have the same hash function and may update its record of the beacon IDs as the beacons 240 updates their beacon IDs. In some implementations, updating the beacon ID is done to prevent spoofing of the beacon 240 and it's data. An example method of encrypting the communication within the PN 200 is described in greater detail in relation to FIG. 3C.

As described above, the beacon 240 can include an anti-spoofing module 242. The anti-spoofing module 242 may ensure the data transmitted from the beacon 240 to the PSS 120 is authentic. As discussed below, in some implementations, the PSS 120 may provide a user 230 with supplemental content when the user's client device 102 is within a predetermined proximity zone of a beacon 240. The supplemental content may be a coupon, loyalty points, or other benefit. Accordingly, a content provider 250 may desire to ensure the client device 102 is actually located in the expected location before providing supplemental content to the client device 102. The anti-spoofing module 242 may use the AES key identifier, location ID, battery level, beacon up time, or a combination thereof to ensure the authenticity of transmitted data. For example, the data packets transmitted to the PSS 120 may be encrypted and include the current battery level and up time of the beacon 240 generating the data packets.

The anti-spoofing module 242 may check that the battery level and up time indicated in the data packets correspond to expected values. For example, if the anti-spoofing module 242 receives a data packet that indicates the up time of a Beacon 240 should be 1 day, 3 hours and 15 minutes, but receives a data packet that indicates the up time is four days, the anti-spoofing module may determine that someone copied the data packets and is attempting to rebroadcast them without revisiting the store. In some implementations, the anti-spoofing module 242 may use a GPS radio or other location service to determine if the data packets are arriving from a location generally associated with the beacon 240. In yet other implementations, the anti-spoofing module 242 may provide the client device 102 with a password or other unique identification number such that the client device 102 may verify to the PSS 120 that the client device 102 is near the beacon 240. The password may be a rolling password. In some implementations, if spoofing is detected the content provider 250 housing the beacon and/or the PSS 120 may be notified. A beacon 240 that is the tampered with or spoofed may be remotely disabled.

In FIG. 2A, the user 230 interacts with a client device 102. As described above in greater detail in relation to FIG. 1, the client may be, but is not limited to, a smart phone, a tablet computer, a laptop and/or a desktop computer. In some implementations, the client device 102 includes a GPS module 222. The GPS module 222 detects the current location of the client device 102 and may transmit the detected location to the PSS 120 via the network 104. The anti-spoofing module in the beacon and/or in the PSS 120, modules 242 and 261 respectively, may receive the detected location and verify the client device 102 is near the reported location of the beacon. For example, the client device 102 may transmit the current location of the client device 102 to the anti-spoofing module 261 of the PSS 120. The PSS 120 may receive a unique beacon identification number. Referencing the beacon location database 265, the unique beacon identification number transmitted to the PSS 120 may indicate the beacon should be located in a particular store of a shopping mall. The current location determined by the gps module 222 may indicate that the client device 102 is in the corresponding shopping mall, and accordingly the client device 102 may be authenticated as being near the beacon 240.

The client device 102 may include a camera 221. The user 230 may use the camera to capture images of merchandise or other content the user prefers. For example, if a user 230 finds a jacket that the user 230 may want to purchase at a later date, the user 230 may use the camera 221 to capture an image of the jacket. In some implementations, the captured image may remain on the client device 102, and in other implementations they are transmitted to the PSS 120 to be stored in the user preference database 267.

User preferences may include, but are not limited to, preferred content providers, preferred content, preferred colors, preferred price points, locations, preferred looks, preferred fashion styles, preferred users, or any combination thereof. For example, using the user interface discussed below, the user 230 may select a jacket the user likes. The jacket may then be saved to the user's preferences. In some implementations, the user 230 may view or change the stored user preferences via the PSS 120. Responsive to those preferences, the PSS 120 may deliver supplemental content to the user. For example, after a user has stored a number of preferences the PSS 120 may send the user 230 a recommendation for pants that match the jacket the user 230 is viewing. The pants may be in a color and a price point the user 230 indicated that she liked in her saved preferences.

The client device 102 may also include a wireless module 223. In some implementations, the wireless module 223 may detect the broadcast from the Beacon 240. As described above, the broadcast may include the unique beacon identification number and other data. The other data may include a password, location data, system status data, system statistics, or any combination thereof. For example, the beacon 240 may include current battery levels in the data broadcast. In some implementations, the data packet in the broadcast may be only a few bits in size. Using the wireless module 223 the client device 102 may transmit the data packet to the PSS 120 on behalf of the beacon 240. In some implementations, the client device 102 forwards the data to the PSS 120 without reading (or decrypting) the data within the data packets.

Still referring to FIG. 2A, and in more detail, the PSS 120 includes a plurality of modules and databases. In some implementations, the PSS 120 is a computer program running on a central server. In other implementations, the PSS 120 is a distributed system running on a plurality of computer servers. For example, the PSS 120 may be replicated across a plurality of servers or specific functions of the PSS 120 may be executed on specific computer servers.

The PSS 120 may include an anti-spoofing module 261. Discussed in greater detail with the anti-spoofing module 242 of the beacon 240, the anti-spoofing module 261 ensures the authenticity of the data received from the client device 102 and/or Beacons 240. For example, the PSS 120 may receive data from the client device that includes the up time of a beacon 240. The anti-spoofing module 261 may compare the up time with an expected up time to ensure the data is authentic. For example, if the up time is only 470 hours when it should be 1,213 hours, the anti-spoofing module may determine that the data was recorded and a third party is attempting to spoof the data to receive supplemental content such as reward points from the PSS 120.

The logistics module 262 of the PSS 120 may provide the content provider 250 with logistical data. For example, the logistics module 262 may monitor the number of client devices 102 that detect a specific beacon identification number over a given period of time and determine the content (or merchandise) near those beacons is more popular than the content near beacons 240 whose beacon identification numbers are not detected as often over the same given time period. The logistics module 262 may also monitor customer flow patterns through the content providers. The content providers 250 may make decisions on where to place content based on the data returned from the logistics module 262. For example, a content provider 250 may place popular content near the back of the store such that a user will have to pass less popular content to get to the more popular content.

The PSS 120 also includes an interface 263. The interface 263 is discussed in greater detail in relation to the exemplary embodiments described in Section C. Briefly, the interface 263 provides a means for a user 230 and/or content provider 250 to interact with the PSS 120. In some implementations, the interface 263 is a plurality of web pages. In other implementations, the interface 263 is a computer program running on the PSS 120 and/or on a client device 102. There may be multiple versions of the user interface 263. For example, there may be one user interface for content providers 250 and another user interface for users 230. In certain implementations, the user interface 263 that is displayed to the user 230 may be responsive to the type of client device 102 used to view the user interface 263. For example, the user interface may appear different when a user views the interface 263 on a smart phone as compared to if the user views the interface 263 on a personal computer.

The first type of interface 263, a content provider interface, (also referred to as a console) may be the interface presented to a content provider 250 upon logging into the PSS 120. The content provider interface may allow a content provider 250 to upload, to the content database 266, descriptions and details of supplemental content 251, images of content 215, availability of content 215, or any combination thereof. Additionally, the content provider 250 may upload coupons and/or benefits to the content database 266 via the content provider interface. For example, the content provider 250 may upload a benefit to the content database 266 that indicates the content provider will be having a sale on Memorial Day. Accordingly, users viewing the user interface may be presented with the details of the Memorial Day sale. The console for a content provider 250 is described below in relation to Section G.

In other implementations, the PSS 120 may provide, through the user interface 263, a platform for the user 230 to barter or haggle over the price of a piece of supplemental content 251 with the content provider. In these implementations, the content provider 250 may use the content provider interface to define minimum acceptable prices for supplemental content 251 in the content database 266 or to define other rules that may govern the bartering and haggling process.

In another implementation, the content provider interfaces may allow for the control, configuration, and management of beacons 240. Beacon management functions of the content provider interface may include such functions as updating firmware; configuring the hours of operation for the beacon; setting a logical radius; updating the PSS 120 as to the physical location of the beacon; and checking beacon settings, statistics, and current status (e.g., battery life). The console for PSS 120 administration is described further in relation to Section G.

In some implementations, the content provider interface is displayed via a computer program or webpage that interacts directly with the PSS 120, which in turn transmits the above described configurations and settings to the beacon 240. In other implementations, the content provider interface is displayed by a program or webpage executing on a mobile device. The mobile device may then allow for the direct configuration of the beacon 240. For example, the mobile device may connect directly to the beacon 240 by Bluetooth to deliver new configuration files, firmware updates, and/or settings to the beacon 240.

The second type of interface 263, the user interface, may be provided to the user 230 when interacting with the PSS 120. The exemplary embodiments discussed in Section F provide a detailed description of the user interface. Briefly, the user interface, may allow the user to view the supplemental content 251 available by the plurality of content providers 250. For example, the user interface may allow the user 230 to view or search for black high-heels available for sale by one or more stores using the PSS 120. Other searches performed by the use 230 aim include searching for content within a specific location, distance from a specific location, price range, color, size, or any combination thereof.

In some implementations, the user 230 may input preferences to the PSS 120 via the user interface. These preferences may be saved into the user preference database 267. The preferences may be directly input into PSS 120 (e.g., the user may indicate they prefer Nike tennis shoes) or the PSS 120 may infer the user's preferences. In inferring the user's preferences, the user may “like” (or select) a plurality of content items. The PSS 120 may then determine similarities between the selected content to determine the user's preferences. In some implementations, selecting a preferred content item may include selecting the image of the content item as it is displayed to the user 230 via the user interface 263. In yet other implementations, the user 230 may upload images captured with the camera 221 to user preference database 267. In yet other implementations, a first user 230 may use selected content of a second user 230 to augment the preferences of the first user 230.

The PSS 120 also includes an analysis module 264. In some implementations, responsive to the preferences of the user 230 stored in the user preference database 267, the analysis module 264 provides the user 230 with supplemental content 251 the user 230 may like. The supplemental content 251 provided to the user 230 may include coupons, benefits, links to other content or any combination thereof. In some implementations, the selection of the supplemental content 251 is responsive to the location of the client device 102. For example, when a user 230 enters the proximity zone of a beacon 240 and the PSS 120 determines the client device 102 is at a specific location, the analysis module 264 may then analyze the user preferences stored in the user preference database 267 and provide supplemental content 251 for the user 230 responsive to the user's preferences and the current location of the user. For example, the analysis module 264 may determine a user is viewing sweaters within a specific store. Analyzing that a high percentage of the captures images of clothes the user uploaded to the PSS 120 include green articles of clothing, the analysis module 264 may suggest to the user 230 to view the content provider's selection of green sweaters, located at the front of the store. In another example, the supplemental content selected by the analysis module 264 may be responsive to only the user's current location. In some implementations, selected supplemental content 251 is associated with a competitor of content item near the user. For example, when viewing a pair of pants in a first store, the analysis module 264 may send the user a coupon for a pair of similar pants at a second store.

As described herein, the supplemental content 251 selected by the analysis module 264 can include coupons, ads, product information or any combination thereof. In certain implementations, the supplemental content 251 is time sensitive. For example, a coupon may be issued by the analysis module 264 and only be valid for the next 10 minutes. In some implementations, the analysis module 264 issues a time sensitive coupons when it has determined the user 230 may be uncertain if they wish to purchase the content item near the user. For example, the analysis module 264 may determine that the user 230 has lingered in the vicinity of the content item for a set period of time (e.g. five minutes), and determined the user 230 is unsure of the purchase. The analysis module 264 may provide the user 230 with a coupon in order to persuade the user 230 to purchase the content item.

In yet other implementations, the analysis module 264 may incorporate the data of the content database 266 and the content provider database 268 to provide the client device 102 with supplemental content that is information about content provided by a competing content provider 250. For example, the analysis module 264 may determine that a client device 102 is in a store viewing shirts. Incorporating the data of the content provider database 268 and the content database the analysis module 264 may provide the user with supplemental content 251 that provides the user with additional information about the shirt near the user. The information may include availability, sizing information, information about similar content items, or general information about the product.

In some implementations, the analysis module 264 provides the user 230 with information when the client device 102 is not in the proximity zone of a beacon 240. For example, the analysis module 264 may determine that the user 230 has uploaded a number of jackets and determines the user may be actively looking for a new winter coat. The analysis module may search the content database 266 and the content provider database 268 to determine if any content providers 250 in the general area currently have sales on jackets. In yet other implementations, the content providers may place bids on the opportunity to provide the user 230 with a coupon or supplemental content. Ad auctions are described further in relation to Section H.

C. Communication with the Beacon and Determining Microlocation

In some implementations, the beacons 240 can be placed in a location without providing the beacons 240 with a power connector or a connection to the network 104. For example, and as described above, the beacons 240 can include a battery 243 that is configured to power the beacons 240 for a least 1 month, 3 months, 6 months, or a year without needing to be replaced or recharged. In some implementations, the beacons 240 do not have a direct connection to the network 104. As described further below, in these implementations, the beacons 240 can communicate with the PSS 120 through the data connection of a client device 102. This can allow a content provider store owner to place a beacon 240 without first setting up a network 104 within the store or running power to the location where the store owner wishes to place the beacon 240.

FIG. 2B is an illustration that provides further detail about the interconnectivity between some of the components of the PN 200. In brief, FIG. 2B illustrates a plurality of client devices 102, each at different distances from a beacons 240. As described above the client devices 102 are connected to the PSS 120 via a network 104. A logical radius 271 extends a first distance from the beacons 240 and a physical radius 272 extends a second distance from the beacon 240 s.

As described above, the beacons 240 transmits a wireless signal, such as a Bluetooth signal. The greatest distance the wireless signal may be received by a client device 102 is the physical radius 272 of the beacon 240. In some implementations, a logical radius 271 may also be set for the beacon 240. The logical radius 271 may be any radius within the physical radius 272. In some implementations, more than one logical radius 271 may be set for each beacon 240. In some implementations, crossing a logical radius 271 may cause an event, such as the delivery of supplemental content, to occur. Client devices 102 in different sections of the beacon's broadcast range may be treated differently. For example, different content may be delivered to client devices 102 within the logical radius 271 as compared to client devices 102 outside the logical radius 271 but within the physical radius 272. In some implementations, the logical radius 271 may be set via the PSS 120. Although the beacon 240 is represented as broadcasting a wireless signal in an omnidirectional manner, one of average skill in the art will recognize that the wireless signal may be tuned such that the wireless signal is not omnidirectional.

FIG. 2B illustrates client devices at three distances from a beacon 240. As illustrated, client device 102(1) is within the inner proximity zone 270. Client devices 102(2) are beyond the logical radius 271 but within the physical radius 272, and therefore within a second proximity zone 280. Client device 102(3) is outside the physical radius 272, and therefore not within one of the proximity zones. In some implementations, the PSS 120 may not deliver content to a client device 102 unless the device is within a logical radius 271. In some implementations, the PSS 120 may determine that a client device 102 is leaving the proximity of the beacon 240 when the client device 102 progresses from the inner proximity zone 270 to an outer zone 280 In some implementations, the PSS 120 may deliver different supplemental content to the client device 102 responsive to if the client device 102 is entering or leaving the inner proximity zone 270.

As described above, in some implementations, the beacon 240 does not communicate directly with the PSS 120. The beacon may communicate with the PSS 120 via at least one client device 102. In some implementations, the beacons 240 and a client device 102 may communicate with one another using a first wireless standard and then the client device 102 and the PSS 120 may communicate with a second communication standard. For example, the beacon 240 may transmit a packet containing data, which is received by the client device 102(1), using the low power Bluetooth standard. The client device 102(1) may then forward the data packet to the PSS 120 using a second communication standard. For example, the client device 102(1) may use its cellular connection or a Wi-Fi connection to forward the data packet to the PSS 120. In some implementations, the device 102 retransmits the data packet to the PSS 120 without accessing, reading, and/or modifying the data packet. In some implementations, the device 102 may append a device identifier, such as a MAC address to the data packet.

The data packet can include information related to the beacon identification number or other data pertaining to the beacon 240. For example, the beacon 240 may relay information about its current power levels or conditions to the PSS 120 via the data packets. In some implementations, the beacon 240 transmits the data packet to a plurality of client devices 102 for forwarding to the PSS 120.

In some implementations, the PSS 120 may transmit data back to the beacon 240 through the client device 102. For example, the PSS 120 may select a client device 102 within the physical radius 272 (or logical radius 271) of the beacon 240. The PSS 120 may then send a data packet to the client device 102 using the second transmission protocol. The client device 102 may then forward the data packet to the beacon 240 using first data transmission standard. The PSS 120 may transmit the data packet to a plurality of client devices 102 within the physical radius 272. The redundancy of the data transmission to the beacon 240 may ensure the data still arrives to the beacon 240 even if the first client device 102 leaves the physical radius 272 before the data is fully transferred to the beacon 240. For example, if client device 102(1) and client device 102(2) both receive the data packet from the PSS 120, if client device 102(2) leaves the physical radius 272 before the data packet can be forwarded to the beacon 240, client device 102(1) can still forward the data packet to the beacon 240. In some implementations, the data that the PSS 120 transmits to a beacon 240 can include configuration files or firmware updates.

FIG. 3A is a flow chart of an example method 300 for determining the location of a client device 102 and providing to the client device 102 with supplement content. The method 300 includes receiving, by the client, a beacon identification number (step 301). The client then transmits the beacon identification number (step 302) to the PSS 120. Responsive to transmitting the beacon identification number, the client receives supplemental content (step 303) from the PSS 120. Responsive to receiving the supplemental content, the supplemental content is displayed on the client (step 304).

As set forth above, at step 301, the client device 102 receives a beacon identification number. In some implementations, the beacon identification number is received by the wireless module 223 of the client device 102. In other implementations, the client 102 may receive the beacon identification number by taking a picture of a QR code placed on or the beacon 240 or through some other non-wireless transmission means. For example, the user may manually enter the beacon identification number into a computer programming running on the client device 102. As discussed in relation to FIG. 2A, the beacon identification number may be accompanied by a data packet that may include beacon statistics or other data.

At step 302, the client device 102 transmits the beacon identification number to the PSS 120. In some implementations, the client device 102 is Internet enabled and transmits the beacon identification number to the PSS 120. The client device 102 may add a client and/or user identification to the beacon identification number when forwarding data to the PSS 120 from the beacon 240. Transmitting the beacon identification number may also include transmitting additional client device 102 or user 230 information to the PSS 120. For example, when a beacon identification number is transmitted, the client may also transmit shopping preferences the user recently entered into a computer program executing on the client device 102. In other implementations, the beacon 240 is Internet enabled, and transmits client identification to the PSS 120 directly responsive to detecting a client device 102 in the proximity zone.

At step 303, in some implementations, the client device 102 receives supplemental content. The supplemental content may be delivered to the client device 102 from the PSS 120. As discussed above, the supplemental content may be a coupon, offer, or other information. For example, the supplemental content may be a coupon for the supplemental content 251 near the beacon 240, an offer for a competitor of the content provider 250 currently providing the content which the client device 102 is near, or the supplemental content may be information indicating to the user additional supplemental content 251 that may complement the currently viewed supplemental content 251.

At step 304, the supplemental content is displayed to the user. In some implementations, the supplemental content is displayed to the user 230 via a computer program executing on the client device 102. The user 230 may only receive the supplemental content if the user 230 is actively using the computer program. In other implementations, the supplemental content may be pushed to the client device 102 and displayed to the user regardless if the user 230 is actively using the computer program. In yet other implementations, the user may only receive the supplemental content if the user is using the computer program and specifically requests the supplemental content to be delivered. For example, a user 230 may be viewing a sweater located near a beacon 240. The user 230 may wish to see if the store is selling any pants that would match the sweater. The user 230 may then activate the computer programming running on the client device 102 and request the PSS 120 to provide the user 230 with a plurality of matching pants in the current and/or competing stores. In some implementations, the plurality of matching pants, or other supplemental content, is ranked based on the user's preferences stored in the user preference database 267.

FIG. 3B is a flow chart of a method 350 for determining the location of a client device. The PSS 120 receives a data packet (step 351). The PSS 120 determines which beacon 240 generated the data packet (step 352). The PSS 120 then determines the location of the of the beacon 240 that generated the data packet (step 352). The PSS 120 then associates the location of the beacon 240 that generated the data packet with the client device 102.

As set forth above, the method 350 begins when the PSS 120 receives a data packet. In some implementations, the data packet is generated by a beacon 240 that is one of a plurality of beacons 240. The data packet can be transmitted from the beacon 240 to the client device 102 using a first wireless standard, and then the client device 102 forwards the data packet to the PSS 120 using a second wireless standard. In some implementations, the client device 102 may append a client device identifier to the data packet when the client device 102 forwards the data packet to the PSS 120.

At step 352, the PSS 120 determines which one of the plurality of beacons 240 generated the data packet. In some implementations, the data packet received by the PSS 120 includes a beacon identifier. The PSS 120 can used the beacon identifier to determine which one of the beacons 240 generated the data packet. In some implementations, the client device 102 that forwards the data packet to the PSS 120 may be within the physical radius 272 of a plurality of beacons 240. In these implementations, the client device 102 may receive a data packet from each of the plurality of beacons 240. The client device 102 or PSS 120 may determine with which of the plurality of beacons 240 has the strongest wireless connection. The client device 102 may forward only the data packet from the beacon 240 with which it has the strongest data connection to the PSS 120. In some implementations, the client device 102 may rank the strength of the connections to each of the plurality of beacons 240 and then forward an indication of the ranking to the PSS 120. The PSS 120 may use the indication of the ranking to better determine the position of the client device 102.

At step 353, the PSS 120 determines the location of the beacon 240 that generated the data packet. As described above, the location of each of the beacons 240 can be saved into the beacon location database 265. The PSS 120 can access the beacon location database 265 and search the beacon location database 265 to retrieve the location of the beacon 240 that generated the data packet.

At step 354, the PSS 120 associates the location of the beacon 240 with the client device 102. For example, determining that the client device 102 forwarded a data packet from a beacon 240 that is located within the men's section of a store, the PSS 120 may determine the client device 102 is also within the men's section of the store. As described, above in relation to step 352, in some implementations, the client device 102 may receive and forward a plurality of data packets form a plurality of beacons 240. The PSS 120 may use the ranked list of connection strength to each of the beacons 240 to triangulate a more specific location of the client device 102. In some implementations, when only data packets form a single beacon 240 are forwarded to the PSS 120, the PSS 120 may determine how far the client device 102 is from the beacon 240 response to the signal strength of the connection the client device 102 establishes with the beacon 240. For example, the PSS 120 may determine if the beacons 240 is within a specific logical radius 271 of the beacon 240.

As described above, in some implementations, the communications between the beacon 240, client 102, and PSS 120 are encrypted. The signal broadcast by the beacon 240, for example, a Bluetooth low energy signal, can be detected by devices not part of the PN 200. For example, the signal may be detected by a laptop running packet sniffing software or the signal may be detected by third party applications executing on the client device 102. For example, a third party may attempt to maliciously determine the user's location by loading software onto the client device 102 and recording the beacon IDs detected as the client device 102 visits different locations using the PN 200. To protect the privacy of users and to ensure the authenticity of communications, the beacon 240, client 102, and PSS 120 may encrypt their communications such that even if a third party did detect the signal from a beacon 240 it would not be able to ascertain useable information from the signal.

FIG. 3C is a flow chart of an example method 370 for encrypting data transmissions when determining the micro-location of a client device. At step 371, the PSS 120 receives data from the client device 102. In some implementations, the data includes an encrypted portion and an unencrypted portion. As described below, in some implementations, the data originates from a beacon 240. The data is broadcast by the beacon 240 and received by the client device 102, which forwards the data to the PSS 120.

The above discussed beacon identifier is stored in the encrypted portion of the data packet. Other data that can be used to ensure the authenticity of the communication is also stored in the encrypted portion. For example, an indication of the time the data packet was transmitted, the up-time of the beacon 240, or similar data may be stored in the encrypted portion. In some implementations, the beacon identifier includes GPS coordinates or a text string that identifies the beacon 240 to the PSS 120. The encrypted portion of the data can also include information regarding the beacon 240, such as, but not limited to, battery level and firmware version. In some implementations, the beacon 240 repeatedly transmits the same encrypted portion for a predetermined amount of time. For example, the beacon 240 may encrypt and broadcast its current up time and beacon identification number for five minutes. After the five minute period, the beacon 240 may generate a new encrypted portion that includes the beacon identification number and the present up time.

During manufacture, the beacon 240 is coded with a key, for example a 16 bit-AES key. When broadcasting data, the beacon 240 uses the key to encrypt data that it broadcasts. In some implementations, the beacon's key is updated randomly or periodically. For example, the beacon 240 may include a shared secret that is hashed with a challenge (e.g., the current time) to create a new key.

The unencrypted portion of the data may include a key hint and a local-ID. As described in greater detail in relation to step 372, the PSS 120 may select a key to decrypt the encrypted portion of the data using the key hint. The local-ID may be used by the client device 102 to determine if it has recently received data from a specific beacon 240. As the actual identification of the beacon 240 is securely stored within the encrypted portion of the data, the client device can identify broadcasts from beacons 240 by the local-ID and does not have to decrypt the data. For example, a client device 102 may receive three data packets, the first with a local-ID of A, the second with a local ID of B, and a third with a local ID of A. Responsive to the local ID, the client device 102 can determine that the first and third data packets came from the same beacon 240. In some implementations, the client device 102 may disregard the third data packet since it already received a data packet from that beacon in the recent past. In some implementations, the local-ID is a 16-bit identifier. At random intervals, each beacon 240 updates its local ID.

At step 372, the PSS 120 selects a key to decrypt the encrypted portion of the data. In some implementations, when the PSS 120 receives encrypted data from a client 102, the PSS 120 does not know which beacon 240 in the PN 200 generated the data. As each beacon 240 in the PN 200 encrypts its data with a unique key, the PSS 120 must determine which key to use to decrypt the data. The PSS 120 stores each of the keys required to decrypt data sent from each of the beacons 240 PN 200. In some implementations, the key hint is part of a key-value pair, and once the key-hint is received by the PSS 120, the key-hint may be passed through a hash function to retrieve the decrypt key from a hash table. In some implementations, the key hint is not unique, such that the location of the beacons 240 cannot be mapped by a third party. In some implementations, a geo-hash, or another indication of the beacon's general location, is transmitted in the unencrypted portion. The PSS 120 may use the geo-hash in combination with the key hint to determine which key to use to decrypted the data. For example, a PSS 120 may receive a key hint of “DFCD 3454.” The PSS 120 may then use the key hint to determine that beacon A has a key of “DFCD 3454 XBEA 788A 351A” and is located in California, beacon B has a key of “DFCD 3454 DPIO 89VA 478B” and is located in Massachusetts, and beacon C has a key of “DFCD 3454 78DA DPE7 3487” and is located in Georgia. The PSS 120 may then determine that the geo-hash is associated with Massachusetts and select the key of “DFCD 3454 DPIO 89VA 478B”, associated with Beacon B, to decrypt the data. In some implementations, the PSS 120 may not require a geo-hash, and may iterative try each of the keys located with the key hint.

At step 373, the data is decrypted. Using the key selected in step 371, the PSS 120 decrypts the encrypted portion of the data. In some implementations, the PSS 120 also authenticates the sender (i.e., the client device or application) transmitting the data to the PSS 120. The PSS 120 may determine if the user of the client device 102 has agreed for their location to be determined and that the application that forwarded the data to the PSS is allowed to receive location data.

At step 374, the beacon identification number is retrieved from the decrypted portion of the data, and at step 375 the PSS 120 determines the micro-location of the beacon associated with the beacon identification number. The method for determining the micro-location of the client device 102 is described above in relation to method 350.

D. Smart Store

FIG. 4A illustrates a schematic overview of a smart store using beacons 240. In some implementations, the beacons 240 are used by the PSS 120 to determine the relative location of client devices 102 within a store or other premise and deliver content to the client device 102 responsive to the client device's location. FIG. 4A illustrates a smart store 400. Three beacon 240(1)-240(3) (generally referred to as beacons 240) are place within the store 400. Beacon 240(1) is placed near the entrance to the store 400. Beacon 240(2) is placed near the display 402(1), which is displaying produces 404(1) and 404(2). Beacon 240(3) is placed near the display 402(2), which is displaying products 404(3) and 404(4). A client device 102(1) is within the physical radius 406(3) of beacon 240(3) and a client device 102(2) is within the physical radius 406(1) of beacon 240(1). As illustrated there is no client device 102 within the physical radius of beacon 240(2). The client devices 102(1) and 102(2) have established a wireless connection with beacons 240(1) and 240(3), respectively. The client devices 102(1) and 102(2) have also established a connection with the PSS 120 through the network 104. The PSS 120 includes the same components as the PSS 120 descried in relation to FIG. 2A.

In the example illustrated in FIG. 4A, the beacon 240(1) is placed near the entrance of the store 400 such that it can detect when a new client device 102 enters the store 400. As illustrated, the client device 102(2) has just entered the store 400 and is within the physical radius 406(1) of the beacon 240(1). While within the physical radius 406(1) of the beacon 240(1), the client device 102(2) may receive data packets with beacon identifiers from the beacon 240(1). The client device 102(2) may then forward data packets to the PSS 120 through the network 104. As described above, the PSS 120 may then lookup the location of the beacon 240 identified by the beacon identifier that was transmitted to the PSS 120 by the client device 102(2). For example, after receiving the data packet and beacon identifier from the client device 102(2), the PSS 120 may determine that the client device 102(2) is near beacon 240(1) and is therefore near the entrance of the store 400.

The client device 102(1) may transmit data packets with deacon identifiers associated with beacon 240(3), and the PSS 120 may determine that the user of the client device 102(1) is viewing products 404(3) and 404(4). As described above, the PSS 120 may transmit supplemental content related to the products 404(3) and 404(4) to the client device 102(1). In some implementations, the PSS 120 may send supplemental content generally related to the store 400 to client device 102(2) when the PSS 120 determines that the client device 102(2) entered the store. For example, the PSS 120 may transmit a coupon for 15% off any product 404 in the store 400 to client device 102(2). The supplemental content deliver to client device 102(1) may relate more specifically to the products 404(3) and 404(4). For example, the PSS 120 may deliver a coupon for 15% off of product 404(4) to the client device 102(1) or the PSS 120 may deliver additional information regarding product 404(4) to the client device 102(1).

In some implementations, supplemental content can be advertisements, coupons, additional information, or suggested products. The PSS 120 may determine what type of supplemental content to deliver to a client device 102 responsive to the user preferences of the user associated with the client device 102 or the preferences of the owners and managers of the store 400. For example, the store owners may wish to reward repeat customers. In this example, a coupon may be delivered to a client device 102 if the client device 102 is determined to be near the location of beacon 240(1) a predetermined number of times within a predetermined number of days. For example, the PSS 120 may deliver a 20% off coupon to a user if the user visits the store five times in one month. In some implementations, beacons 240 may be placed outside of a store or in a location within the store 400 such that the physical radius 406 of the beacon 240 may cover areas outside the store 400. For example, the owner of the store 400 may place a beacon 240 outside the store 400 such that the PSS 120 can determine when a registered client device 102 is walking by the store and deliver supplemental content to the client device 102.

FIG. 4B is a flow chart of a method 450 for delivering supplemental content to a client device 102 in a smart store environment. The method 450 includes receiving user preferences (step 451) and receiving content provider preferences (step 452). The method 450 further includes associating a beacon with a location (step 453). The method 450 can also include receiving a beacon identification number from a client device (step 454). Responsive to receiving the beacon identification number, it is determined that the client device is within a predetermined radius of the location (step 455). The type of supplemental content or response that should be provided to the client is then determined (step 456). Responsive to the response determination, the supplemental content is delivered to the client device (step 457).

As set forth above, the method includes receiving user preferences (step 451) and content provider preferences (step 452). In some implementations, the preferences of the user 230 and/or content provider 250 may be updated, added, or removed at any time. For example, the user may see an item for sale online and save it to their account to update the user's preferences. The content provider's preferences may include, but are not limited to, notifications regarding discounts on content, global use coupons, a list of competitors and/or collaborators, a list of preferred users, content inventory, or any combination thereof. The list of collaborators may be business associations that sell complementary items. For example, near Valentine's Day a local florist may enter into collaboration with a local confectioner, such that if a user 230 purchases content at one of the stores, the user 230 will automatically receive a coupon at the other store. Similarly, the content provider 250 may wish to keep a list of customers that, on average, spend a set dollar amount with the content provider each month, quarter or year. In turn, the content provider may have a preference to automatically provide those customers with discounts, coupons, benefits, or other supplemental content.

At step 453, a location is associated with the beacon. The location of the beacon is stored in the beacon location database 265. As described above, responsive to receiving a beacon identification number, the PSS 120 looks up the beacon location with the beacon identification number in the beacon location database 265. The PSS 120 then associates the location of the beacon with the location of the client device 102. In some implementations, before the PSS 120 can associate the location of the beacon 240 with the client device 102, the PSS 120 needs to be provided the location of the beacon 240.

At step 454, the PSS 120 receives the beacon identification number from a client device 102. As discussed above in relation to method 350, in some implementations, the beacon identification number is accompanied by a user identification number.

At step 455, responsive to receiving the beacon identification number, the PSS 120 determines the location of the client device 102 (step 454). In some implementations, the PSS 120 compares the received beacon indemnification number with a table of beacon identification numbers stored in the beacon location database 265. The beacon location database 265 may then provide the PSS 120 with the location of the beacon 240. In some implementations, the location includes a physical location of the content provider 250 and/or the location of the beacon 240 within the content provider 250. Responsive to determining the location and/or location of the beacon 240, the PSS 120 may cross reference the determined location of the beacon 240 with the current location of the client device 102 to authenticate the received beacon identification number. In some implementations, the client device 102 may deliver to the PSS 120 the strength of its connection with the beacon 240 such that the PSS 120 can determine if the client device 102 is within a logical radius of the beacons. In some implementations, the PSS 120 may wait for the client device 102 to be within the logical radius of the beacon 240 before transmitting supplemental content to the client device 102.

At step 465, the PSS 120 determines a response based on location, user preferences, and content provider preferences. In some implementations, the calculated response is a determination of the type of supplemental content to be sent to the client device 102. In some implementations, the response based on the location of the beacon 240, the user's preferences, the content provider's preferences, or any combination thereof. In some implementations, the user 230 may specify the type of response the user 230 would like to receive. For example, the user 230 may request a necklace to complement the currently viewed dress based on the preferences the user has uploaded to the PSS 120. As another example, the user may request a coupon for the currently view content or a list of similar items the user is currently viewing.

At step 457, responsive to determining the response, the PSS 120 transmits the response to the client device 102. As discussed in reference to method 300, in some implementations, the response is transmitted to the client only when requested by the user 230. In other implementations, the response may be automatically calculated and delivered to the client device 102 without intervention by the user.

The skilled artisan will understand that, although the method steps above are shown in a particular order, they can be done in any order, or certain steps may be skipped entirely.

E. Exemplary Implementations of the System

Having described the components of the system, an example of a user 230 interacting with the system 200 may provide further details and context for understanding the system and methods disclosed herein. While the below example particularly show and describe specific implementations, it should be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the system and methods described in this disclosure.

As a basis for the example, the PSS 120 hosts a website that the user 230 may access via a client device 102, such a web enabled smart phone or home computer. Furthering the example, the content providers 250 may be a clothing merchant that sells clothing through its retail outlets or stores. Within those outlets the clothing merchant places beacons 240 throughout the store. The merchant may then list the merchandise available at the store with the PSS 120. Additionally, the PSS may gather images of merchandise from non-content providers, such from the website of fashion magazines.

In this example, a user may view clothing, accessories and other merchandise on the website hosted by the PSS 120. As the user views the items on the website, the user may mark items they like or dislike. The system may then use the characteristics of these items to update the user's shopping and merchandise preferences. The website saves the user's preferences and “liked” items so the user may view details about them at a later time or share the details with friends via the website. For example, a group of friends may send each other images of dresses they like for an event, or a user may view the items save by a fashion forward movie star or other fashion opinion leader.

These details may also be saved, synced, and/or accessed by the user's smart phone. In this example, the user's smart phone may include a computer program that syncs with the PSS 120. Additionally, the smart phone may be Bluetooth enabled such that it can detect the presence of a beacon.

Now referring back to the clothing store of content provider. The merchant can place a number of beacons around the store, for example, at the entrance to the store and near a table of dresses. In a manner completely transparent to the user, when the user enters a beacon-enabled, clothing store the user's phone may recognize the beacon. The beacon may send the phone a identifier, which the phone retransmits to the PSS 120. The PSS 120 resolves the identifier and determines in which store the beacon is located and the beacon's location within the store. Accessing the user's preferences, the PSS 120 may determine specific items the user may like.

As this process is transparent to the user, the user's experience of walking into a beacon-enabled store is as follows. Within a few moments of walking into the store, the user's phone alerts the user that the store has a dress similar to the dress the user recently indicated liking on the website hosted by the PSS 120. Additionally, the user may receive information about the dress such as availability, location with the store, and price. The user may also receive a coupon for 10% off from the merchant as a thank you for having visited the store multiple times within the last week.

Next, the user may walk to table displaying the dress. The table contains a beacon. As the user nears the table the user's phone detects the beacon and, as described above, relays the beacon's identification to the PSS 120. Knowing the location of the beacon, the PSS 120 can estimate that the user is viewing the dress.

Not seeing the dress in the user's size, the user may request assistance from a store employee via the program running on the phone. Additionally, if the user accesses the program while in the store the program may automatically display information about the merchandise at the nearest beacon. In this example, rather than asking for assistance from an employee, the user may access the program on the user's phone, which automatically reveals information about the dress the user is viewing. This information may reveal to the user the store currently has three of the dresses in the user's size in the store's back storage area.

The system, having noticed the user has been near the beacon corresponding to the dress for some time without moving on, may predict the user has mixed feelings about purchasing the dress. After the user has been in close proximity to the dress for a few minutes, the PSS 120 may automatically deliver to the user's phone a coupon for the dress that is valid for only the next 10 minutes.

F. Exemplary Implementations of a User Interface

As discussed above, the PSS 120 includes an interface module 263. In some implementations, the interface module 263 generates a user interface and a content provider interface. The interfaces may be a website executing on the PSS 120 and/or another central web server. In some implementations, the client device 102 executes a computer program that interfaces with the PSS 120. In other implementations, the client device 102 includes a web browser that views the website pages provided by the PSS 120 and/or other central web server. The exemplary implementations below represent a possible user interfaces that may be viewed as a webpage and/or as a graphical user interface of a computer program interacting with the PSS 120.

FIG. 5A is a first page of an exemplary implementation of a user interface. The user interface displays a plurality of content items 501 that are available from one or more content providers 250. In some implementations, the displayed content items 501 can be filtered. For example, the user 230 may request that only men's fashions be displayed or only supplemental content 251 from a particular content provider 250 be displayed. The user interface also includes a number of buttons 502(1)-502(n). The exemplary implementation of FIG. 5 includes 5 buttons. The buttons may be “soft buttons” that update according to the current page of the user interface that is currently displayed. In other implementations, the buttons 502 are constant throughout the plurality of pages of the user interface. In some implementations, the user may select displayed content. Selecting the displayed content add and/or updates the user's preferences.

Similarly, in FIG. 5B the exemplary user interface is displaying a plurality of content providers 250. In some implementations, the plurality of content providers 250 is all content providers 250 that are in the PN 200. In other implementations, the displayed content providers 250 are a sub-population of the total number of content providers 250. For example, the user 230 may wish to only display content providers 250 that have been selected by the user 230 and/or only content providers 250 that are within a given distance of the current location of the user 230. In some implementations, the user may select content providers to add to the user's preferences.

FIG. 5C is an exemplary implementation of the user interface displaying content providers 250 within a given location of the user 230. In some implementations, the nearby content providers 250 are displayed on a map 504. The content providers 250 may be marked on the map 504 with an indicator 505. The user 230 may set the scale of the map 504, and the number of displayed content providers 250 may update as the user 230 pans and zooms the view of the map 504.

In some implementations, the choice of content provider 250 to display on the map 504 is responsive to the user preference and/or content provider preferences stored in the PSS 120. For example, the user interface may only display content providers 250 that the PSS 120 has determined the user has a high probability of having an interest. In other implementations, the selection of the content providers 250 to display may be based on the preferences of the content providers 250. For example, the content providers may wish to have the PSS 120 provide, via the user interface, coupons to a specific demographic of user within a 2 mile radius of the content provider.

FIG. 5D is an exemplary implementation of the user interface displaying additional information regarding a content provider 250. In some implementations, responsive to selecting an indicator 505 on the map 504, additional information is provided to the user regarding the selected content provider 250. Additional information about the content provider 250 may be displayed in a window 506 that is overlaid on the map 504. The window 506 may display, but is not limited to displaying, the content provider's name, location, contact information, availability of content, and available supplemental content.

FIG. 5E is an exemplary implementation of the user interface for displaying supplemental content to a user 230. FIG. 5D lists a plurality of supplemental content 507 currently available to the user 230. In some implementations, the user 230 may save specific supplemental content for later use. As described above, in some implementations, the displayed supplemental content 507 is global supplemental content. Global supplemental content may be supplemental content that is available to all users of the PN 100. In other implementations, the displayed supplemental content includes supplement content 507 that is specifically selected for and/or by the user 230.

FIG. 5E is an exemplary implementation of the user interface for displaying the user's profile. In some implementations, the profile page may act as the hub of the user interface. For example, the user may add, remove, or change preferences. In some implementations, the user 230 may change system preferences on the profile page. In some implementations, system preferences may change the way the user 230 interacts with the user interface or how content providers 250 are allowed to interact with the user 230. In some implementations, the profile page includes a window 508 that displays current or recent activity. The number of new items may also be represent to the user as a notification icon 509 that is always viewable to the user 230 when the user 230 is using the user interface.

G. Exemplary Implementations of a Backend System

As described above, the PSS 120 includes an interface module 263. In addition to the user interface descried above, the PSS 120 may also provide a content provider interface and system management interface. The content provider interface may provide content providers 250 with an interface for performing actions such as updating supplemental content (e.g., coupons) and changing beacon parameters (e.g., logical radii settings). The system management interface may allow the manager of the PSS 120 to perform functions such as, but not limited to, adding new content provider accounts and associating beacons 240 with specific content providers 250.

Management of Content Providers

The interface module 263 may provide the manager of the PSS 120 with a system management interface (also referred to as the console) for managing various aspects of the PSS 120. These aspects may include adding and removing content providers 250 from the PSS 120 and associating beacons 240 with specific content providers 250. As described above, the console or other interface may be provided in the form of a webpage, web application, and/or computer program. The interface may be accessed and/or executed by various types of computing devices, such as desktop computers, laptops, smart phones and/or tablet computers.

In some implementations, the PSS manager may use the console to add content providers 250 to the PSS 120. For example, the PSS 120 may be managed by a company that sells and/or licenses accounts to content providers 250. The manager of the PSS 120 may create a PSS account for the content provider 250 responsive to selling and/or licensing a PSS account to the content provider 250. The content provider 250 may provide information to the PSS manger. The PSS manger may then use the information to setup a PSS account for the content provider 250. The information may include an account name, account manager information, number of properties (e.g., stores) in which the content provider 250 may be using the beacons 240, the number of beacons 240 the content provider 250 is requesting (or purchasing), number of user logins to be associated with the PSS account, and any special instructions for the PSS manager. The PSS manager may future associate licensing restrictions with the content provider's 250 PSS account. The licensing restrictions may include the length of the license and the features of the PSS 120 the content provider 250 is licensed to use. Optional features to license may include content management and publishing, offers management, in-store beacon management, and analytics capabilities.

Responsive to creating the content provider's 250 PSS account, the PSS manager may associate an account administrator to the PSS account. The account administrator may be an employee of the content provider 250 responsible for managing the PSS account. Managing a PSS account may include adding and removing authorized account users and managing the content provider's 250 PSS preferences.

As described above, the content provider 250 may be a store. In some embodiments, the content provider 250 may own or manage a plurality of properties. For example, the content provider 250 may be a chain, which operates one or more stores in one or more cities. In some embodiments, the account administrator may group its plurality of properties responsive to a set criteria. For example, the plurality of stores may be grouped responsive to a geographic location. In some embodiments, the account administrator may group its plurality of properties based on a scheme that mirrors the content provider's 250 business structure. For example, the content provider 250 may divide its stores into sales regions. When grouping the plurality of properties associated with the PSS account, the account administrator may group the plurality of properties such that the groups align with the sales region.

In some implementations, one type of authorized user may be a group administrator. The group administrator may be responsible for one or more groups associated with the content provider's 250 PSS account. Continuing the above example, the system user responsible for a group may be a regional manager for a sales region. Another type of authorized user may be the role authorized user. The group administrators may create role authorized users and assign predetermined responsibilities to the role authorized users. Example responsibilities (or roles) may include content creator, offers manager, data analyst manager, and beacon manager. In some implementations, the content creator may create, manage, and publish content provider assets and product merchandising. The offers manager may create and manage the personalized supplemental content provided to users 230. The data analysis manager may generate and view reports created by the PSS 120 and the analysis module 264. The beacon manager may activate and deactivate beacons 240 and set beacon parameters such as location and the above described logical radius 271. In some implementations, authorized users may be created which are not assigned specific roles. These authorized users may log into a content provider's 250 PSS account to view information, but may not be authorized to perform tasks associated with the above described roles.

One or more of the authorized user types may be authorized to perform various administrative functions. For example, an administrative function may include sending messages to the authorized users associated with the content provider's 250 PSS account. In some implementations, the messages may be sent to a specific type of authorized user. For example, the messages may be sent to only the beacon managers. Administrative functionality may also include resetting and/or retrieving passwords, performing system audits, and creating user directories.

FIG. 6 is a flow chart of the hierarchical relationship between the authorized user types described above. As an overview, the PSS manager 600 is the highest level authorized user. The PSS manager 600 may manage the PSS 120. The PSS manager 600 may sell the services of the PSS 120 to n content providers 250. For each content provider 250, the PSS manager 600 may create an account manager 601. The account manager 601 may then create one or more group managers 602. Each group manager 602 may then create one or more role authorized users 603. The role authorized users 603 may then create one or more authorized users 604. In some implementations, a user type may create and/or manage user types below it on the relationship tree.

Management of Beacons

In some embodiments, the PSS manager licenses and/or sells the beacons 240 to content providers 250. In some embodiments, specific functions of the beacons 240 may need to be managed by the content provider 250 and/or the PSS manager. For example, the PSS manager may activate and deactivate beacons 240 responsive to the start and end of a licensing agreement with a content provider 250. The content provider 250 may manage beacon parameters such as the logical radius 271. In some implementations, beacons 240 may be managed by one or more of the above described authorized user types.

In some implementations, the PSS manager may maintain a database of the beacons 240 within the PN 200. The database may include the beacon's 240 serial number, MAC address, manufacturing data, manufacturer, version number, firmware version number, shipment date, associated content provider 250 and case type. The PSS manager may populate the database prior to sending the beacons 240 to the content provider 250.

Responsive to receiving the beacons 240 from a PSS manager, the content provider 250 may log into the console and set various beacon parameters. In some embodiments, the parameters may include beacon placement, the size of the logical radius 271, and the active/inactive state. In some embodiments, via the console, the beacon manager may also view beacon status reports for the beacons 240 under its management. The information may include the version number of the beacon 240, battery level, activation state, and up time.

Management of Supplemental Content

An authorized user may manage the content provider's 250 supplemental content and the content's distribution through the console. The content provider 250 may create and manage conditions that govern the distribution of supplemental content. The conditions may include store segments, audience segments, event triggers, and user parameters. As described below, the conditions may be created and applied to one or more supplemental content items. By reusing conditions and rules, the authorized users may reduce the time required to create supplemental content.

One exemplary embodiment of a condition is a store segment condition. In some embodiments, the above described groups may also be further divided into store segments to provide greater control in where supplemental content is distributed. The store segments may incorporate one or more parameters. For example, a content provider's 250 stores may be segments based on the store's performance and/or location. In some implementations, a store may belong to more than one segment. For example, a content provider's 250 store in New York City may belong to a New England segment, a New York state segment, a New York City segment, and a high performance segment.

An audience segment condition may be another exemplary embodiment of a condition. The audience segment may allow supplemental content to be provided to only specific users 230. Audience segments may include one or more parameters such as, but not limited to, the number of visits within a given time range, the age of the user 230, and the gender of the user 230. For example, a user 230 may be included in a first audience segment if the user 230 visits the content provider 250 more than three times in the last month, is between the ages of 18 and 34, and is female.

The delivery of supplemental content may be triggered responsive to an event condition. These event conditions may be referred to as offer trigger events. A number of parameters may be associated with the offer trigger. The parameters may include location, beacon reference, delay time, dwell time, and default status. For example, an offer trigger that occurs when a user 230 enters a content provider's 250 store may include the parameters: title=Walk in Instant; Beacons=All; Delay time=0 sec; default=yes.

Having created the conditions that may control the distribution of the supplemental content, the authorized users may create the supplemental content. The supplemental content may be placed in an offer queue that dispenses the supplemental content. In some implementations, multiple offer queues may be created. In some implementations, multiple offer queues may be created; however, only one may be active at a given time. For example, an offer manager may create offer queues for each season and then activate the seasonal offer queue during the correct season. The supplemental content may include one or more parameters. The parameters may include supplemental content value (e.g., 30% off or $10 off a purchase of $50), start date, end date, start time, end time, barcode image, supplemental content code, expiration time, exclusions, frequency cap, sharing option, and template. The template may layout and design (i.e., the visual presentation) of the supplemental content. In some implementations, the PSS 120 may verify one or more the supplemental content parameters before distributing the supplemental content. For example, the frequency cap of one supplemental content item may be set to 1,000. In this example, if the supplemental content has already been distributed 1,000 times, the PSS 120 may look for another supplemental content item in the offer queue to distribute to the user 230. Responsive to creating the supplemental content, the supplemental content may be associated with an audience segment condition, store segment condition, and/or trigger event condition.

In some implementations, the PSS 120 may determine that a user 230 meets the conditions to receive more than one supplemental content item. In some embodiments, a priority level condition may be assigned to each supplemental content item. The priority level may be used to determine which supplemental content item the user 230 should receive. For example, the offer manager may create supplemental content for loyal customers and give it a higher priority than supplemental content for the general public. Accordingly, in this example, the loyal customer may receive the supplemental content intended for loyal customers over the supplemental content intended for the general public.

In some embodiment, the PSS 120 may include a mechanism for approving supplemental content. In some implementations, offers reducing the price of supplemental content 251 by a percentage or amount over a predetermined limit require approval before the PSS 120 distributes the supplemental content to users 230. The PSS 120 may seek approval for supplemental content my sending a message (e.g., an email message) to the account manager or other authorized user authorized to approval supplemental content.

FIG. 7 is a flow chart of a method 700 for creating, managing, and delivering supplemental content. At step 701, the method 700 includes creating one or more conditions. As described above, the conditions may include audience segment conditions, store segment conditions, and event trigger conditions. In some implementations, the PSS 120 stores the conditions such that they may be used with multiple supplemental content items. At step 702, the supplemental content is created. Creating supplemental content may include associating predetermined parameters with an offer.

At step 703, the supplemental content is approved. In some implementations, the supplemental content may not require approval, and in other implementations, the supplemental content may require approval if the supplemental content includes an offer over a predetermined dollar value.

At step 704, one or more conditions are associated with the supplemental content. As described above, the conditions may include one or more parameters. The PSS 120 may use the parameters within the conditions to determine what supplemental content to deliver to a user's 230 client device 102.

At step 705, the PSS 120 receives a beacon identification number from a client device 102. In some implementations, step 705 may mirror step 453 of method 450 described above. As described above, when a client device 102 is within a predetermined range of a beacon 240, the client device 102 may detect the beacon's 204 beacon identification number. The client device 102 may then transmit the beacon identification number and client device identification number to the PSS 120. Responsive to the beacon identification number and client device identification number, the PSS 120 may retrieve supplemental content that may be appropriate to deliver to the client device 102.

At step 706, the PSS 120 determines which of the supplemental content items retrieved in step 705 should be delivered to the client device 102. The determination may be responsive to the conditions associated with each of the supplemental content items. For example, in step 705 the PSS 120 may retrieve a first supplemental content item with the condition it is to be delivered to female user and a second supplemental content item with the condition it is to be delivered to a male user. The PSS 120 may review these conditions and determine that as the client device 102 is associated with a male user, the second condition should be delivered. At step 707, the supplemental content is delivered to the client device 102.

The skilled artisan will understand that, although the method steps above are shown in a particular order, they can be done in any order, or certain steps may be skipped entirely.

H. AD Auction

As described above, in some implementations, a beacon 240 can be placed in a store. In some implementations, the store may sell a plurality of products from a plurality of venders (or content providers). For example, a home improvement store may sell ten different types of lawn mowers produced by three different venders. As described above, the PSS 120 may send supplemental content to a client device 102 when the client device 102 is within a predetermined range of a beacon 240. In implementations, when the beacon is placed near the products of a plurality of venders, the PSS 120 may hold a content auction to determine what supplemental content is delivered to the client device 102.

FIG. 8 illustrates an example environment 800 for an content auction. As illustrated, products 801(1)-801(4) (collectively referred to as products 801) are for sale in store 802. A beacon 240 is placed near the products 801. The beacon 240 can communicate with a client device 102 within the beacon's physical radius 803. As described above, the client device 102 is in communication with the PSS 120 through the network 104. The PSS 120 of FIG. 8 is illustrated including a content database 804, a transaction database 805, and an auction module 806. Any component described in relation to a PSS 120 can be included in any other PSS 120 described herein. The environment 800 also includes a plurality of content providers 807 that generate supplemental content to be delivered to the client device 102. In some implementations, the content provider 807 are the venders of, or otherwise associated with, the products 801.

In FIG. 2A, the PSS 120 of FIG. 8 can also include a content database 804. The content database 804 can be database where the PSS 120 stores the supplemental content generated by the content providers 807. The content stored in the content database 804 can be stored in the content database 804 in association with a bid price and at least one beacon 240 or beacon location. For example, a content provider 807 may be willing to pay $3.00 for one of its supplemental content items to be delivered to client device 102 when the client device 102 is near the content provider's product 801.

The PSS 120 may store the results of past auctions in the transaction database 805. In some implementations, the content providers 807 may set a cap on the amount of money they wish to spend on auctions within a predetermined amount of time. The PSS 120 may store this information in the transaction database 805 and determine if the content provider 807 has enough money left in their allowance to place a bid in an active auction. For example, a content provider 807 may wish to spend no more than $1,000 on auctions per month. In this example, if the content provider 807 has already spent $998.00 on auctions in the month, the transaction database 805 may prohibit a $3.00 bid from being placed for the content provider's account. The transaction database 805 may also be used to general reports for billing purposes at the predetermined intervals. For example, the owner of the PSS 120 may create invoices for each of the content providers 807 using an interface to the transaction database 805.

The auction module 806 may conduct the auction to determine what supplement content is to be delivered to the client device 102. For example, responsive to the PSS 120 determining the client device 102 is within the physical radius 803 of the beacon 240, the PSS 120 may transmit supplemental content to the client device 102. The PSS 120 can access to the content database 804 to determine what content is associated with the beacon 240. In some implementations, the auction module 806 may access the transaction database 805 to determine if the content associated with the beacon 240 is eligible for an auction. Content may be ineligible for an auction if, for example, the content provider 807 wishes to spend a predetermined amount on auctions per month and that amount has been met for the month. The content provider's content may not be eligible for auctions until the content provider's budget renews at the beginning of the next month.

Responsive to determining what content is associated with the beacon 240, the auction module 806 conducts the ad auction. In some implementations, the auction module 806 iteratively increase the price for sending the supplemental content item to the client device 102 until a winner of the auction is determined. For example, if the auction module 806 determines that content item A, B, C, and D are associated with products 801(1), 801(2), 801(3), and 801(4), respectively, it may enter the content items A, B, C, and D into the ad auction. In this example, if content item A has a maximum bid price of $3.00, content item B a maximum bid price of $5.00, content item C a maximum bid price of $2.00, and content item maximum D a bid price of $3.00. The auction module 806 may increase the bid price of the auction until a winner is determined. The increase in bid price may be a fixed or variable amount. Furthering the above example, assume the increase price is $0.10. In this example, content item C would drop out once the bid price reaches 2.00 and content items A and D would drop out when the bid priced reaches 3.00. Content item B would win the auction at a price of 3.10. In some implementations, auction module 806 calculates the winning price as the second maximum highest bid price, which is to be paid by the content provider associated with the highest bid price. In this example, the second highest bid price is $3.00, which would be charged for displaying content item B. In some implementations, if the highest bid price is associated with more than one content item (for example, if the above example action also included content item E with a maximum bid price of $5.00), the winner of the auction may be determined by randomly selecting one of the content items that has the highest maximum bid price. In some implementations, with multiple highest maximum bids, each of the content items with the highest maximum bid may be queued for subsequent delivery to client devices 102. For example, content item D may be delivered to the first client device 102 and content item E may be queued for display to the next client device 102 that enters the physical radius 803. Once the queue is empty ad auctions may resume to determine which content items are delivered to client device 102 entering the physical radius 803.

FIG. 9 is a flow chart of a method 900 for conducting an ad auction. At step 901, the PSS 120 receives a plurality of supplemental content items. The plurality of supplemental content items can be received from one or more content providers 807. In some implementations, a maximum bid price and a specific beacon 240 are associated with each of the supplemental content items. In some implementations, the supplemental content items can be associated with a plurality of beacons 240. For example, a content provider 807 may sell grills through a national retailer. In this example, the content provider may associate their supplemental content items with each of the beacons located near the grilling section of each of the national retailer's stores. As described above, the maximum bid price is the maximum price the content provider 807 is willing to pay for the supplemental content item to be delivered to the client device 102.

At step 902, the PSS 120 receives an indication of a client device 102 location. As described above in relation to FIG. 8, the PSS 120 may determine the location of a client device 102 by receiving a beacon identification from the client device 102 once the beacon 240 has crossed the physical radius 803. The PSS 120 may then determine the location of the beacon 240 that generated the beacon identification number and then associate the location of the beacon 240 with the client device 102.

At step 903, the PSS 120 selects a portion of the plurality of supplemental content items responsive to the location of the client device 102. For example, the auction module 806, may search the content database 804 for content items that are associated with the location indicated in step 902. The PSS 120 may then enter the selected content items into an ad auction to determine which content item is to delivered to the client device 102.

At step 904, the PSS 120 selects a supplemental content item responsive to the bids associated with the each of the plurality of supplemental content items selected in step 903. As described above, in some implementations, the supplemental content item is selected through an ad auction. In some implementations, responsive to multiple content items having the same maximum bid price, the ad auction can have a plurality of winners. In these instances, the content item to be delivered can be randomly selected from the plurality of winners or the winning content items may be queued for display to subsequent client devices as they enter the physical radius 803 of the beacon 240. Once a content item is selected for display to the client device 102, the price of the winning bid is charged to the account of the content provider associated with the winning content item.

At step 905, the selected supplemental content item is delivered to the client device. The content item may be delivered to the client device via Wi-Fi or a cellular connection of the client device. In some implementations, the content item is only delivered to the client device is actively running an application associated with the PSS 120. In other implementations, the content item may be delivered to the client device 102 as a push notification, and the software application associated with the PSS 120 does not need to be open or active. In some implementations, if the client device 102 remains within the physical radius of the beacon 240 for a predetermined amount of time, the PSS 120 may conduct a second ad auction to deliver a second supplemental content item.
